Question

what is the reproductive system

Answer 1

Reproductive system is the group of organs in charge of procreation and preservation of the human kind. I suppose you're referring to human reproduction - which is sexual - needs a spermatozoon and an egg to be effected.
Female reprod. system is conformed by ovaries, uterus, vagina, fallopian tubes and vulva.
Male reprod. system is conformed by penis, testicles, prostate and seminal vesicles.
Organs that produce the sexual cells, eggs and spermatozoa, are ovaries and testicles, repectively. With coitus, the spermatozoon fecundates the egg and then - a baby will be born.
